     * 待实现的方法：
     * 
     * 1. 订单创建
     *    - OrderDTO createOrderFromCart(String cartId, CreateOrderRequest request)
     *    - OrderDTO createOrder(CreateOrderRequest request)
     * 
     * 2. 订单查询
     *    - OrderDTO getOrderById(String orderId)
     *    - OrderDTO getOrderByNumber(String orderNumber)
     *    - OrderSummaryDTO getOrderSummary(String orderId)
     *    - List<OrderSummaryDTO> getOrdersByUser(String userId)
     *    - List<OrderSummaryDTO> getOrdersByUserAndStatus(String userId, OrderStatus status)
     *    - PageResponse<OrderSummaryDTO> listOrders(String userId, OrderStatus status, int page, int size)
     *    - List<OrderSummaryDTO> getOrdersByDateRange(LocalDateTime startTime, LocalDateTime endTime)
     * 
     * 3. 订单明细
     *    - List<OrderItemDTO> getOrderItems(String orderId)
     *    - int getOrderItemCount(String orderId)
     * 
     * 4. 订单状态管理
     *    - OrderDTO payOrder(String orderId, String paymentMethod, String paymentId)
     *    - OrderDTO cancelOrder(String orderId, String reason)
     *    - OrderDTO refundOrder(String orderId, String reason)
     *    - OrderDTO updateOrderStatus(String orderId, OrderStatus status)
     *    - boolean canCancelOrder(String orderId)
     *    - boolean canRefundOrder(String orderId)
     * 
     * 5. 订单统计
     *    - long countUserOrders(String userId)
     *    - long countUserOrdersByStatus(String userId, OrderStatus status)
     *    - BigDecimal calculateUserTotalSpending(String userId)
     *    - Map<String, Long> getTopSellingProducts(int limit)
     *    - long countOrdersByDateRange(LocalDateTime startTime, LocalDateTime endTime)
     *    - BigDecimal calculateSalesByDateRange(LocalDateTime startTime, LocalDateTime endTime)
     * 
     * 6. 订单清理
     *    - int cancelTimeoutOrders(int timeoutMinutes)
